dpplication filed May 17,

some of which may have a certain degree of transverse motion in order tocompensate for irregularities in the cooperatin guide members or forslight differences in t 1e dimensions of'the sash or window frame. Theinvention also contemplates the provision of guide memberswhichinterengage with their companion guide members so as to prevent lateraldisengagement thereof and which provide for frictional engagementbetween the point of interlocking engagement of the companion membersand one of the adjacent supports.

The invention also has in View the securing of the adjustable 'uiclemember in such relation to its support that it will be free of lostmotion or such amount of clearance as would tend to produce noise whensuch window constructionis applied to various vehicles such as autobusses', street cars, and the like. It also has in view a constructionadapted for a window supplied with counterweights and means hereinafterfully described and providing'a housing for the counterbalance cablewithin one of the guideways. To the accomplishment of the foregoing andrelated ends, said invention, then, consists of .the

particulsrly pointed out in the claims. v

In the construction shown in Figs. 1 and 2, a window construction isprovided wherein a window sash 1 is provided with one side member 2having a groove 3 centrally of its vertical edge, said groove beingenlarged to more than semi-circular cross-section at its inner end 4,and being adapted to receive a substantially cylindrical head 5 providedon a guide member 6 formed of sheet metal pro-' viding a T-shaped footor base 7 which iS adapted to be received within a finishing channelstrip 8, and secured to the window frame 9.

The opposite side member 10 of the sash is provided with a rectangularchannel-way 11 within which is engaged a sheet metal guide member 12providing a groove 13 having rearward extensions 14 which normally arepositioned at a wide angle, as is more clearly shown in Fig. 12. Saidgrooved guide member is adapted to engage over a beaded guide membersimilar to that shown at the opposite side of the window, andillustrated in greater detail in Fig. 11. The grooved guide member isadapted to be frictionally engaged within the channel-way and properallowance for the spring action of the structure must be made.

In the form of construction shown in Fig. 3, a metal guide member 21 issecured to the window-frame, said guide member provid ing a pair ofbeaded guides 22 formed integrally therewith,- and each ositionedcentrally of a channel-way 23 wlthin which the cooperating portion ofthe window sash is engaged.

The window sash is not intended to frictionally' engage the centralparting strip 24 or the adjacent finishing flange 25 of the guidemember. but is en ported entirely upon the beaded guide mem er. The sashmembers 26, 27, for the upper and lower frames of the window, asillustrated in 3, are identical in shape and are provided withrectangular channels 28 in their vertical edges within which sheet metalgrooved guide members 29 are engaged after the manner of thoseillustrated in Figs. 10 and 12. The guide member 21 attached to theframe is provided "with a recess 31 to receive the cable 32 of acounter-balancing device and a pulley 33 mounted in the frame isadapted-to guide the same within said recess which serves as a cablehousing.

The lower end of the cable may be secured to the'sash at any convenientpoint. The upper sash need not be provided with a cable inasmuch asinmany constructions the upper sash is merely locked in position. Theconstruction shown in Fig. 4 provides for the positioning of a doubleguide member 41 upon the window frame, said member being provided with achannel 42 and a groove 43 of more than semi-circular cross-section, andthe securing of the double guide member by means of fastening membersinserted central ly through apertures 44 in the parting strip 45, of theconstruction. With the construction of the type shown in Fig. 4, abeaded guide member attached to the sash of the window of the type shownin Fig. 6, may be utilized.

The form of construction shown in Fig. 6 relates to a single. groovedmember 46 attached to the frame of the window and providing achannel-way 47 to receive the adjacent portion of the sash and a groove48 of more than semi-circular cross-section at its base, and said sashmember having a groove 49 in its lateral edge within which theextensions 51 of a sheet metal guide member 52 providing a bead 53 areadapted to be received. The extensions on the sheet metal guide memberare provided with alined laterally extending slots 53 through which apin 54 is engaged to limit the degree of vertical movement of such guidemember;

Instead of the guidemember shown in Fig. 7 being applied to the windowsash, it may be applied to a supporting member attached to the windowframe, said supporting member 61 having an elongated slot 62 withinwhich the sheet metal guide member 63 is frictionally engaged. The sashmember 64 in such instance will comprise a structure providing a groove65 at its lateral edge of more than semi-circular cross-section toengage about the bead of the guide member on the frame. The sash membershown in Fig. 5 is preferably of extruded aluminum and has a depression66 formed on each side quired without affecting the strength of suchparts. Said side member is provided with a channel 67 opposite itsgrooved portion thereof to improve the appearance of the same to reducethe amount of material rewithin which the window glass 68 and glazv ingrubber 69 is engaged.

When a sheet metal grooved member of the type shown in Figs. 10 and 12is engaged within a channel-way at the side of a window, it is desirableto provide means for limthe upper and lower faces of the side member ofthe sash.

In the construction shown'in Fig. 13, the

beaded guide members 7 3 are provided integrally with the side members74 of the sash and are engaged within the sheet metal grooved guidemembers 75 secured in channel strips 7 6 attached to the frame sides 77.These grooved guide members may correspond in construction with thatshown in Figs. and 12. In place offorming the beaded guide integrallywith the side of the window sash, a beaded guide 81 formed of sheetmetal may be formed and firmly secured to the edge of the side member 82of the sash, as is shown in Fig. 14. In such construction the'guidemember will be engaged With a grooved sheet metal guide member 83 of thetype shown in Figs. 10 and 12. The method of retaining such guide memberwithin the groove in a vertical direction is illustrated in Fig. whereina pin 84 is set through the channel member and engages a pair of alinednotches 85 formed in theextension edges of the resilient grooved guidemember.

The construction just described is adapted for combination with a cable86 of a counterweight. as is more clearly shown in Fi s. 16 and 17. Inthis case the end of the cable is engaged within the sheet metal memberproviding a bead 87 and the groove of the other guide member 88 servesas a channel-way within which the cable is houseda At the upper end 89said grooved channel member maybe cupped to prevent abrasion upon theedge of the cable. A pulley 91 is preferably supportedupon a bracket 92attached to the inner side of the frame 93, said bracket providing apair of flanges 94 between which the pivot pin 95 for the pulley issupported.

In the construction shown in Fig. 18, the grooved metal guide member 101is secured to the window sash 102 by means of a pair of plates 103 ateach end of the channel-way 104:

ilil

lib

.in the respective side members, the grooved guide member terminatingshort of said plates with the ends of its extensions abutting the same.The plates may be formed to press against the heads of screws 105 whichare setdiagonally through the mortised ends of the sash and thus form alock against the disengagement of such diagonal screws.

Another form of construction is illustrated in Figs. 19 and wherein thegrooved sheet metal guide member 106 is provided with spring metaltongues 107 secured at the respective ends of the same, which tonguesare held at their free ends by suitable fastening members 108, such asscrews secured to the base of the groove in the side members 109 of thesash. Apcrtures 111 in the grooved portions' of the guide member, inalinement with the free ends of the tongues, provide for the attachmentand adjustment of the screws. 7

In the construction shown in Fig. 21, a window sash 121, which may be ofwood or metal, or any rigid material, has one side member 122 providedwith groove 123 in its edge having an enlarged terminal portion 124; ofmore than semi-circular cross-section within which a sheet metal guidemember 125 having a bead is adapted to be engaged and interlockedagainst lateral disengagement. Said sheet metal guide member ispreferably secured within a channel member 126, the flanges of whichserve as finishing strips. At the opposite side of the sash a similarconstruction is provided excepting that the side member 127 of the sashis provided-with a channel-way 128 within which a sheet metal groovedguide member 129 is positioned, said guide member having resilienttongues 131 to hold the same from end-wise displacement. Thus with afixed guide member at one side and an adjustable guide member at the0pposite side, a degree of lateral adjustment will be introduced intothe construction suflicient to prevent a degree of friction upon theguide members which would tend to lock the window and prevent its freeadjustment to anydesired position.

In the construction shown in Fig. 22, each side member 141 of the windowsasl i is provided with a channel-way 142 within which a sheet metalgrooved guide member 113 is engaged, said guide member cooperating withasheet met'albeaded guide member 14a secured within a finishing channelstrip 1-15 attached to the frame. This construction has the advantageover the construction shown in Fig. 21 in that it not only compensatesfor irregularities in the vertical members of the window frame butadjusts itself to slight differences in the horizontal members of thewindow frame which may not at all times be at exactly right angles tothe side members. Thus a satisfactory closing of the window may beprovided for at all times through the fact that the window sash is freeto move on its respective guide members to a position which willsquarely meet the adjacent member of the window frame.

/ While grooved and beaded guide members formed of sheet metal have beendescribed and illustrated in most of the forms disclosed, it is tobeunderstood that solid or hollow guide members of metal or othersuitable material may also be used. Also, instead of resilient elementsbeing provided on the guide members, they may be provided on the channelstrips which receive the guide members.
